DESCRIPTION

The ure driver provides support for USB Ethernet adapters based on the RealTek RTL8152, RTL8153/RTL8153B, and RTL8156/RTL8156B USB Ethernet controllers, as well as USB Ethernet PHYs provided by rgephy(4).

NICs based on the RTL8152 are capable of 10 and 100Mbps. NICs based on the RTL8153 or provided by rgephy(4) are capable of 10, 100, and 1000Mbps. NICs based on the RTL8156 are capable of 10, 100, 1000, and 2500Mbps operation.

The ure driver supports the following media types:

autoselect

Enable auto selection of the media type and options. The user can manually override the auto selected mode by adding media options to the /etc/rc.conf file.

10baseT/UTP

Set 10Mbps operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.

100baseTX

Set 100Mbps (Fast Ethernet) operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.

1000baseTX

Set 1000baseTX (Gigabit Ethernet) operation over twisted pair. The RealTek gigE chips support 1000Mbps in full-duplex mode only.

2500base-T

Set 2500Base-T operation over twisted pair. The RealTek 8156/8156B chips support 2500Mbps in full-duplex mode only.

The ure driver supports the following media options for 10/100 operation:

full-duplex

Force full-duplex operation.

half-duplex

Force half-duplex operation.
